Allows you to enable .pof checking, which allows the
remote update block to verify the existence of an
application configuration image before the image is

Description
read_param
Input
No
Read signal for the parameter specified in
param[]
input port and fed to
data_out[]
output port.
Signal indicating the parameter specified on the
param[]
port should be read. The number of bits
set on
data_out[]
depends on the parameter
type. The signal is sampled at the rising clock
edge. Assert the signal for only one clock cycle to
prevent the parameter from being read again in a
subsequent clock cycle.
The busy signal is activated as soon as
read_
param
is read as active. While the parameter is
being read, the busy signal remains asserted, and
data_out[]
has invalid data. When the busy
signal is deactivated,
data_out[]
is valid,
another parameter can be read.
